A hookah (from Hindustani: हुक़्क़ा (), حقّہ ‬ (), IPA: [ˌɦʊqqaː]; also see other names), also known as the ḡalyān (Persian: قلیان), is a single- or multi-stemmed instrument for vaporizing and smoking flavored tobacco (often Mu‘assel), or sometimes cannabis or opium, whose vapor or smoke is passed through a water basin—often glass-based—before inhalation.
